末っ子
すえっこ
- flat (heiban)
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
youngest child
The youngest child is the “end child” — with a little clipped-off pause in the middle.
